***Please Help***

This is my first grow so I'm a newb. I'm 3 wks and 3days into flower and some of my fan leaves are becoming necrotic. It just seems to be creeping up the plants and I'm not sure if i've got a nute defficiancy in the soil ( MG potting) or if this is the natural process. I'm watering every 4-5 days with the ph set at 6.8 and i've been using blackstrap since I started flower.Thanks in advance for all insight.

the plants @ 3 weeks need a big boost of p&k

your plants look a little hungry but overall pretty much on par for the age. if you dont get more of what they need expect more yellowing.

Indica's will show a fair abount of yellowing, especially when fed with FOX Farm nutes

you beat me too it budsoaker- I was gonna say same thing-looks like start of k deficiecny with p right behind it.
nice call

Thanks abud for the quick response. Since I'm using mg potting soil, what would you recommend as a supplement, just to clarify, these are a indica/sativa hybrid.

tiger bloom. anything with low n and high p and k-advise against anything high in n

you responded before I could, thanks for your insight.I'm a total newb so I need some layman terms please.

hope I didn't offend anyone. So I should invest in some tiger bloom even though Im using mg? what strength should the nutes be set? at what point should they be applied? Thanks again for the rapid response.

go to a local store and look at the plant nutrients they have. it'll say n-p-k on evry bottle or jar.youwant one that says like 10-30-10 , or somethin close to that. here's a link for ya , read this it'll be easier. i forgot to say don't give the plants more than a half a dose at one time to begin with.

P-phosphourous and k-potassium- yes to the tiger bloom-the mg is probably the worst stuff a newbie can grow in. I take it you are not feeding any additional nutes at this point? if so, good chance alot of the nutes in the original soil have been consumed. the black strap is good.
